Description

[technical field]

[0001] The invention relates to a medicine Manshanhong soft capsule for warming the lungs and eliminating phlegm, relieving cough and relieving asthma and a preparation method thereof, belonging to the field of traditional Chinese medicines. [Background technique]

[0002] Chronic cough and asthma syndrome caused by cold phlegm involving the lungs, mainly manifested as simple type and wheezing type acute and chronic bronchitis. Breathing and chest tightness, phlegm in the throat, accompanied by lack of thirst, clear and long urine, thin white or greasy tongue coating, stringy and tense pulse.

[0003] Acute and chronic bronchitis is a common and frequently-occurring disease in clinical practice. Especially in recent years, air pollution has become more and more serious, and the incidence rate has also shown an increasing trend year by year. According to reports, the incidence rate of bronchitis in my country is 0.8-2%, and there are about 10-26 million pat...
